Eur J Cancer 2019 Jan 22;109:21-27. Epub 2019 Jan 22.

Medical Oncology Department, Instituto de Investigación Sanitaria la Princesa, HU La Princesa, Madrid, Spain. Electronic address:

Background: Cancer immune therapy has shown remarkable benefit in the treatment of a range of cancer types, although it may initiate autoimmune-related disorders in some patients. We have attempted to establish whether the incidence of irAEs after the use of anti-PD-1 antibodies nivolumab or pembrolizumab in advanced malignancies is associated with anti-PD-1 treatment efficacy.

Patients And Methods: We studied patients treated with single-agent nivolumab or pembrolizumab for advanced cancer. Read More

Mechanistic overview of immune checkpoints to support the rational design of their combinations in cancer immunotherapy.

Ann Oncol 2018 01;29(1):71-83

Department of Clinical Pharmacology, Genentech Research and Early Development, South San Francisco, USA.

Checkpoint receptor blockers, known to act by blocking the pathways that inhibit immune cell activation and stimulate immune responses against tumor cells, have been immensely successful in the treatment of cancer. Among several checkpoint receptors of immune cells, cytotoxic T-lymphocyte-associated protein-4 (CTLA-4), programmed cell death protein-1 (PD-1), T-cell immunoglobulin and ITIM domain (TIGIT), T-cell immunoglobulin-3 (TIM-3) and lymphocyte activation gene 3 (LAG-3) are the most commonly targeted checkpoints for cancer immunotherapy. Six drugs including one CTLA-4 blocker (ipilimumab), two PD-1 blockers (nivolumab and pembrolizumab) and three PD-L1 blockers (atezolizumab, avelumab and durvalumab) are approved for the treatment of different types of cancers including both solid tumors such as melanoma, lung cancer, head and neck cancer, bladder cancer and Merkel cell cancer as well as hematological tumors such as classic Hodgkin's lymphoma.

Servicio de Dermatología, Complejo Asistencial Universitario de Salamanca, Salamanca, España; IBSAL Instituto de Investigación Biomédica de Salamanca, Complejo Asistencial Universitario de Salamanca, Salamanca, España.

The eighth edition of the staging manual of the American Joint Committee on Cancer incorporates important changes in the classification of skin cancers. Coming 40 years after the first edition, the latest manual preserves its specific system for Merkel cell carcinoma and takes into account recent publications on the prognosis of squamous cell carcinoma by defining a completely new T category for this neoplasm. Staging for squamous cell carcinoma considers head and neck tumors (excluding the eyelid) and does not offer solutions for other sites except the vulva, penis, and perianal region. Read More

Constitutive and acquired mechanisms of resistance to immune checkpoint blockade in human cancer.

Cytokine Growth Factor Rev 2017 08 2;36:17-24. Epub 2017 Jun 2.

San Raffaele Scientific Institute, 20132 Milan, Italy.

Cancer immunotherapy with monoclonal antibodies directed against regulatory pathways in T lymphocytes has been revolutionizing medical oncology, and the clinical success of monoclonal antibodies targeting either cytotoxic T lymphocyte antigen-4 (CTLA-4) or program death-1 (PD-1) in patients affected by melanoma, Hodgkin's lymphoma, Merkel cell carcinoma, and head and neck, bladder, renal cell or non-small cell lung cancer is way beyond the most optimistic expectation. However, immune checkpoint blockade (ICB) has failed to arrest progression in a consistent amount of patients affected by those tumors, and various histological types, including breast, colon and prostate cancer, are less sensitive to this therapeutic approach. Such clinical findings have fueled massive research efforts in the attempt to identify pre-existing and acquired mechanisms of resistance to ICB. Read More
